What's the difference between a car's maintenance-free battery and a maintenance battery?

The batteries we often use are mainly divided into three categories, rcommom batteries, dry battery and free maintenance battery.

1 batteries; Batteries of the plate is made up of lead and lead oxide, the electrolyte is sulfuric acid aqueous solution. It is the main advantage of voltage stability, the price is cheap; Weakness is lower than can (that is, the battery storage of electricity per kilogram), short service life and maintenance frequency.

2 dried lotus battery: it is the full name of dry charged lead-acid batteries, it is the main characteristic of negative plate has higher storage capacity, in the condition of dry completely, can save the electricity generated by in two years, when using, need to join the electrolyte, etc. It can be used in 20 to 30 minutes.

3 free maintenance battery: maintenance-free batteries due to its structural advantages, the consumption of the electrolyte is very small, in the service life of the basic don't need to add distilled water. It also has a shock resistant, high temperature resistant, small volume, the characteristics of uniformity. The service life of the general is twice of the batteries. The free maintenance batteries on the market has two kinds: the first in a one-time add electrolyte later use when buying does not need to maintain fluid (add supplementary);Battery itself is another good factory had already added electrolyte and block, users won't add supplementary fluid. General lead-acid battery is made up of positive and negative plate, plate, shell, electrolyte and wiring and other components of the pile head, the discharge of chemical reactions is depend on the positive plate active substances (lead dioxide and pb) and the negative plate active substances (spongiform pure lead) in the electrolyte (dilute sulphuric acid solution), under the action of the plate grid frame, traditional battery lead antimony alloy, maintenance-free battery is made of lead calcium alloy, the former with antimony, the latter with calcium, which is fundamental to both the mark. Different material can produce different phenomena: traditional battery will happen in the process of using liquid reducing phenomenon, this is because the gate frame of antimony can lead pollution on the negative plate spongiform pure, weakened after fully charged battery in the counter electromotive force, caused by excessive water decomposition, a large number of oxygen and hydrogen escape from the positive and negative plates respectively, reduce the electrolyte. Use calcium instead of antimony, can change the counter electromotive force after fully charged battery, reduce charging flow, liquid vaporization rate reduce, thereby reducing the loss of the electrolyte.

Due to the free maintenance battery USES lead calcium alloy grid frame, charging when the water quantity is little, low moisture evaporation, coupled with the outer seal structure, the acid gases released is very few, so it is compared with the traditional battery, do not need to add any liquid, pile head for wiring, wireless corrosion, overcharge resistance is strong, large starting current, power advantages of long storage time.

The listing of mobile phone is used the lithium battery, when they leave the battery has been activated, and lithium electricity no memory pool, so can be used as filling. Before the show when the battery is full of electricity (three times after a full charge can charge more 1-2 hours).

Introduce a few mobile phone charging tips below:

1. Do not excessive discharge. Tips for equipment deficiency of "" "" "" "" should be charged; To the device is automatically shut down before charging, the battery has been excessive discharge. It will affect battery life. So when mobile phone tip low power can be charged.

2. Don't overcharge. The charger with instructions, you should unplug chargers. Now the charger usually have filled with the design of the automatic stop, short time and not taking it from the charger's no harm in the battery, but left the battery charger for a long time, late into the night the grid voltage rise, this has stopped charging the charger, voltage rise, and will continue to charge, battery charging. It will affect battery life.

3. If the battery for a long time not to charge to 60%, alone in a cool and dry place, and every 4 or 5 months to supplement charge.

4. When the charging is not recommended the use of mobile phones, standby charging."

Maintenance-free battery normal charging and discharging, comes from acid mist, water decomposition of hydrogen and oxygen through the catalyst and the pressure inside the battery back into water, when over voltage charging, internal pressure exceeds the setpoint of exhaust valve, just outside, so the electrolyte loss under the condition of normal use.

Maintenance-free battery on a large number of applications in the car now, it is also a kind of lead-acid battery, just acid is adsorbed on the battery plate between the asbestos diaphragm, also called the poor fluid cell in our professional, it compared to common battery, nothing more than the normal charge and discharge from acid mist, water decomposition of hydrogen and oxygen through the catalyst and the pressure inside the battery back into water, when over voltage charging, internal pressure exceeds the setpoint of exhaust valve, exhaust to the outside, so the electrolyte loss under the condition of normal use. When charging, and ordinary battery produces acid mist and hydrogen and oxygen, to the external, need regular supply electrolytic cell, and adjust the concentration of acid.

Above are some differences on the battery performance, now tell me something about the conditions of use, maintenance free storage battery on the conditions of temperature and the demand is higher, when high voltage charging, the internal pressure exceeds the threshold threshold will consume water and acid, and general repair shops cannot be added to, so the reply after the performance degradation performance more bad, also because of its battery is barren solution, large current discharge ability is relatively poor, with capacity of less than ordinary battery.

Early use ordinary lead-acid battery for his car, now there are still many vehicles, ordinary lead-acid batteries for full, electrolyte battery internal resistance is small, large current discharge performance is good, so more suitable for large starting current car, when a high voltage charging, can timely exhaust, won't produce internal high pressure, there will not be a blow up of maintenance-free batteries, and because of its each battery isolation by liquid mouth, can regularly check the filling the electrolyte, so won't produce deficient fluid show plate problem, as long as the regular maintenance, its service life is much higher than from WeiHuXing, and its use in open environment, can escape the acid mist dispersed in time, won't cause corrosion of vehicles, the main problem is to prevent leakage, do this, ordinary batteries are better than free WeiHuXing.

Difference is that the battery in the running process of water consumption,

Maintenance-free battery in differentiate not to come out on appearance, only the battery model to have difference.

The key to maintenance-free batteries in the battery plate contains antimony decreases, and ordinary plate no this aspect of the control of the battery. To avoid maintenance battery low water consumption, the consumption of batteries more than water, so the probability of maintenance-free battery and water is low.
